12 Claims.

This invention relates to radiators, and particularly to an improvedconstruction of a section thereof. 7

The present invention is particularly well adapted for use in radiatorsections comprising a plurality of connected tubular portions, and isintended primarily for use in the end section of a radiator.

One object of the present invention is to provide a radiator section ofnovel construction which may be readily adapted for use in various typesof heating systems as, for example, one or two pipe steam, hot water orvapor systems.

Another object of the invention is to provide a construction of radiatorsection which will insure the ready removal of air from the entireradiator, including the upper and lower portions thereof, therebyproviding for quicker and more uniform heating of the radiator.

A further object of the invention is to provide a radiator sectionembodying a structure whereby the section may be adapted to numeroustypes of heating systems, thereby permitting a single pattern to servein the construction of radiator sections for use in difierent systems,and avoiding the necessity of providing different patterns for sectionsused in the various systems.

A still further object of the invention is to improve devices of thecharacter described in sundry details hereinafter referred to, andparticularly pointed out in the appended claims.

One embodiment of the present invention is shown, for illustrativepurposes, in the accompanying drawings, in which Fig. 1' is a sideelevational view of a radiator section embodying features of the presentinvention;

Fig. 2 is a vertical longitudinal sectional elevation of the structureillustrated in Fig.1, and 4c taken substantially as indicated by theline 2-2 thereof; 1

Fig. 3 is a side elevational view of a radiator comprising a pluralityof sections, the end oneof which has a portion thereof broken away toillustrate the application of the present invention thereto;

Fig. 4 is an elevational view of an ordinary automatic airvalve whichmay be employed under certain conditions in conjunction with my improvedradiator structure; and

Figs. 5, 6, 7 and 8 are fragmentary sectional elevational views of theupper portion of a radiator section embodying my improved constructionand illustrating the manner of its use in various types of heatingsystems.-

Referring particularly to Figs. 1 to 4, inclusive, of the drawings, theillustrative embodiment of the present invention is shown in conjunctionwith a radiator section comprising a plurality of verticallydisposedsubstantially parallel tubular portions 1a, lb and 10 adapted tocommunicate with each other adjacent their upper and lower ends, itbeing understood that the invention may be employed in conjunction withradiators of various other constructions.

Positioned preferably adjacent the upper end of the central orintermediate tubular portion 1b of the type of radiator shown is ahorizontal partition 2 extending across the interior'of the tubularportion and providing lower and upper chambers 5 and 10, respectively,within the section, the partition 2 having an upwardly extending lugllformedintegrally therewith and extending partially across the interiorof the tubular portion within the chamber 16. The horizontally disposedpartition is provided with a passage extending therethrough comprising,in the present instance, a vertically disposed port 3 and a transverselyor horizontally disposed aperture 18 formed in the lug l1 and extendingoutwardly to the exterior of the radiator section.

Formed also in the radiator section 1 are a plurality of openings 12,13, 1 and 15 which may be screw-threaded for the reception of connectingnipples for connecting adjacent sections in the usual manner, and bywhich communication between adjacent sections may be established, or ifthe improved section is employed as an end section of a radiator unit, aplug 17 may be positioned in the opening 12 as illustrated in Figs. 1and 2, and if the section is employed in a one-pipe system, the opening.14 may be closed by a plug or. closure 16 as illustrated in Fig. l.

Formed also in the body of the section and communicating with thechamber 10 is an aperture 6 into which a plug 7 may be screw-threaded,and below the partition 2 is formed an aperture 9 communicating with thechamber 5 and adapted to receive a screw-threaded plug 8.

Screw-threaded into the aperture 18 formed in and extending through thelug i1 is a plug 4', preferably of greater length than the plugs 7 and8, it being understood thatthe apertures 6-, l8 and 9 are preferably ofsubstantially uniform size or diameter so that, if desired, the plugs'7, 4 and 8 may be interchangeably positioned in the respectiveapertures for adapting the improved section to various types of heatingsystems as illustrated in Figs. 5 to 8, inclusive.

Referring to Figs. 5-, 6, 7 and 8, Fig. 5 illustrates the use of myimproved radiator section in a one or two-pipe steam or vapor systemafter the manner of an ordinary unimproved section with the plug 4 ofFig. 2 having been replaced by the plug 7, and an automatic air valve 19of well known construction positioned in the aperture 6 from which theplug 7 has been removed from the position shown in Fig. 2, therebyproviding communication between the chambers 5 and 10 and permitting thecirculation of steam or vapor in the usual way.

It has been found, however, that in such an arrangement, through theupper portion of the radiator and, in the usual manner, acts to closethe air valve 19 before all of the air has been expelled from thecentral portions of the radiator, thereby retarding the passage of steaminto certain of the sections and causing the center to be air bound andretard heating of the radiator.

To overcome this condition, particularly in a one-pipe steam or vaporsystem, the long plug 4, as shown in Fig. 6, is positioned in theaperture 18 in a manner to close the passage through the partition 2-and prevent communication betwee the upper end of the chamber 5 and thechamber 19. In such a case, the plug '7 may be replaced in the aperture6 and the air valve 19 positioned in the aperture 9 communicating withthe chamber 5. With the arrangement shown in Fig. 6, any steam passingquickly through the upper portion of the radiator unit is required topass downwardly, in the type of radiator section shown in Fig. 1,through the tubular portions 1a and 10, through the lower end of'theradiator and thence upwardly through the central or intermediate tubularportion 1b before reaching the air valve, thereby permitting the airfrom the lower central portion of the radiator unit to be dischargedthrough the air valve before it is closed by the action of the steam. Itwill be observed that by such an arrangement, the air is completelydischarged from the entire radiator unit before the steam acts to closethe valve.

The arran ement shown in Fig. 7 is particular ly well adapted fortwo-pipe steam or vapor systems where a trap is used and no air valve isneeded, the plugs 4 and 7 having been reversed placed by a manuallyoperated air valve 20 in the aperture 6 for removing trapped air fromthe upper part of the radiator unit.

It will be observed from the foregoing description and by reference toFig. '1, that if desired, or in an emergency, my improved radiatorsection, with the plugs 4, "I and 8 positioned as shown in Fig. 7, maybe used as an intermediate section of a radiator unit merely by removingthe plug 17 from the opening 12 and connecting up the improved sectionwith adjacent sections by the use of nipples in the well known mannerand as above described.

It will be observed also from the foregoing description that the presentinvention provides a novel construction and arrangement of a radiatorsection which may be readily adapted for use steam frequently passesquickly.

in various types of heating systems, and wherein by proper arrangement,the removal of air from the entire radiator unit including the upper andlower portions thereof may be accomplished, thereby providing quickerand more uniform heating of the radiator.

Obviously, the present invention is not limited to the preciseconstruction and arrangement shown and described as the same may bevariously modified. Moreover, all the features of the invention need notbe used conjointly as the same may be used to advantage in variouslydifferent combinations and sub-combinations.
